This work examined the supply response of selected export and food crops using a selection of seven countries from the Economic Community of West African States (ECOWAS). The three export crops considered are cocoa, coffee and cotton while the food crops considered are maize and cassava. The inter-country comparism of supply response of export and food crops selected for this work indicated that elasticities are different from country to country. The Perron s crash and growth changestructural break test reveals that in Ghana, structural adjustment programme, SAP, has a positive and significant effect on the growth in the trend of cocoa acreage, cocoa yield, cassava acreage and maize yield. SAP has a positive and significant effect on maize producer price and cocoa yield in Nigeria. In Cote d Ivoire, SAP only has a positive effect on cocoa yield and cassava producer price. Results for Mali, however shows that SAP significantly and positively increased the growth in the trend of cotton yield, cassava acreage, maize acreage, and cassava yield.
